UNIT D STATES To all whom it may concern:

Be it known that I, JOHN J. REED, of Lyons, in the county of Clinton and State of Iowa, have invented a new and useful Illlprovement in \Vindmills, of which the following is a specification.

1 The object of my invention is to construct a windmill that shall be self-adjusting to the direct-ion of the wind without usin gextra vanes 1 to move the wheel in and out of the wind.

My invention consists in a wheel hung to swing in a horizontal plane, and having a vane hung on the wheel to swing in the same plane,

the normal position of the vane being slightly inclined to the axis of the wheel, so that the wheel is held by the vane with its edge more or less presented to the wind, according to the pressure. This movement is regulated by an adjustable weight connected with the wheel.

Myinvention consists, also, inbrakemechanism of novel construction, and in certain novel details of construction, which will be described hereinafter with. reference to the accompanying drawings.

In the drawings, Figure l is a sectional side elevation of my improved windmill. Fig. 2 is a plan view, with the wheel and vane swung at right angles to each other. Fig. 3is a rear elevation, with the parts in position as shown 0 by Fig. 2.

' Similar letters of reference indicate corresponding parts.

A is the wheel, of common construction, carried by shaft to, that is supported in suita- 3 5 ble bearings on the frame B, which is fitted to turn horizontally on a supporting-pivot, 0,

at the top of the tower. O is the vane, attached on the frame B by hinge-joints b so as to swing horizontally, or in practice so that 0 while the vane is held by the wind the wheel may swing by the force of the wind. As

shown by dotted lines in Fig. 2, the vane rests normally against a rubber stop, 0, that projects from an arm, 61,01 frame B, which arm 5 and stop prevent swinging movement in one direction, and retain the vane at a slight angle to the shaft to. Upon the arm (1 is hung an angle-lever, 0, connected by a link, f, to the vaneO, and carrying on its outer arm,

which is horizontal, or nearly so, an adjustable 5o weight,-g. The weight 9 tends to throw the vane G and shaft a into line, and by adjustment of the weight to or from the fulcrum of the lever c it will act with more or less power.

Upon the back of the wheel A is fixed a brake-wheel, h, which, as shown, is attached by arms to the spider of wheelA.

. Upon the frame B is hung a crank-lever, i, one end of which projects behind the brakewheel h, and is fitted with a friction-shoe for hearing on the same, while the other end of the lever 2' projects at the side of frame B, so

as to come in contact with the vane-staff or projection therefrom when the wheel and vane are turned 011 the joints b. A spring, a, from the frame B acts to hold the lever 6 free from wheel It.

In operation, the tendency of the windpressure is to swing the wheel and spider, the vane being held to the wind, and raise the weight g. This tendency is resisted by the weight g until the pressure increases above the point for which the weight is set, and the wheel then swings with its edge more or less to the wind. If the pressure is sufficient to force the wheel entirely out of position the leveri is brought into contact with the vane, and the shoe at its other end is pressed against the brake-wheel h to stop the revolution of the wheel.

For throwing the wheel out of gear by hand, I provide a lever, 7c, hung on the frame B, and connected by a link, I, with lever c.

A rope or wire, on, passes through the tubular pivot 0 of frame-B into the tower, so that 85 by drawing on the rope the lever k will be moved, lever e raised, and the vane and wheel A swung out of the wind.

By this construction the wheel is rendered self-adjusting to the force of the wind without 0 complicated mechanism, and without the use of a separate vane.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In windmills, the pivoted frame B, supporting the wheel A, and provided with the arm (I, the vane O, hinged to the frame B, and
